Spamlist blackhole.compu.net now returning 100% FALSE POSITIVES

This is an urgent message to those using blackhole.compu.net as a DNS
SPAM Blacklist. It was a default list in ORFilter, as well as other
lists.

It appears that this DNS black list ceased operation a couple of years
ago, and the owners are now returning a FALSE POSITIVE RESULT for all
requests. This means that ALL mail will be being blocked as SPAM if
you are blocking SPAM based on this list.

I don't know how many this will affect, but we were using a default
setup in ORFilter, and it was in there.

he got me too!
:-(
I'm administrating a network since 2 month on my own. the person who
did that before was more handy than me so I trusted him, but this was a
real mistake from him. Mail is that important, I had checked each BL
twice before I had trusted it. But as you say, it was default-setting
from ORfilter.

so, what I'm going to do now is, testing all of my Blacklists

Doesn't sound like that to me, just a guy who doesn't see why he should
pay for all the traffic his domain is still getting from morons.

Bulldust. No such thing. The mail servers in question are looking up his
server that does not exist.

If his server didn't exist, there wouldn't be a problem.

You'd think that this would be a preferable solution to sending false
positives.

Sending false positives will force the brain dead admins to get their
act together.
